"ap lication filed April 10, 1912'. Serial No. 689,887.

To all whom it may concern: Be it known that I, J OHN G. Knns'r, acitizenof the United- States, residing at Springfield, in the county ofSangamon and State of Illinois, have invented'new and usefulImprovements in Plowing-Machines, of which the followingis aspecification. This invention relates to the class of plows and morespecifically tothat class of plowing machines which comprise aipluralityof plow blades and which are commonly called gang plows.

An object of this-invention is to provide a gang plow which has disposedthereon a plurality of helical screws which cotiperate withthe plowblades in the manner set forth hereinafter. i Another object ofthisinvention is to provide a plowing machinewhich is constructed of buta few parts and one which isdurable, easy to control and eflicient inoperation.

VViththe above and otherobjects in view,

my invention relates to such details of con- T is connected with themain frame 1 andstructionand in the arrangement and combination of theseveral parts as will be hereinafter fully described 1 and specificallypointed out in the appended claims.

In describing my inventionin detail referencewill be had tothe'accompanying drawings wherein like charactersdenote like orcorresponding parts throughout the several views and in which, i

Figure 1 is a plan view of my invention, the engine and its controllingclutch and lever being-removed for clearness. Fig. 2isa side elevationthereof. Fig. 3 is a plan View of my invention showing the specificmeans for controlling the engine, in detail. Fig; 4 isafront elevationof my'invention. Fig. 5 is a detail view. Fig. 6 is a detail sectionalview of themounti'ng castingfor the plow beams and drive shafts.

Referring'now tothe drawings wherein is illustrated the preferred formof my invention, the numeral 1 designates the main frame, which frame isspanned by the cross pieces 2, the saidfcross pieces being connected bythemembers 3. A U-shaped frame has mounted thereon brackets 4 throughwhich brackets extend the shaft 5 as is clearly'shown; The shaft, 5 issupported at each extremity by the traction wheels6 and has keyedthereo'n a gear-'wheel 8, the gear The movement of the lever let occurswhen the lever 15 is rocked upon its pivot 16, the lever 14 beingengaged by its bifurcated end 17.

For the purposeof supporting the bracket 18 which has journaled theretothe stub shaft 19, the hail20 is swung upon the under side of the frame7. The stub shaft 19 is supported intermediate its ends by the bracket21 which is carried upon the standard 22 andis provided at one end witha gear wheel 23 which receives motion from the gear wheel 8. The otherend of the stub shaft is supported upon the member 24 by means of thebracket 25 and has thereon a second gear wheel 26 which gives motion tothe pinions27 and 28 journaled respectively on the stub shafts 32 and31. Struck down portions 29 are provided in the pieces 22 and 24 andareprovided with bearings 30 and 30 which support the stub shafts 31 and32 which carrythe pinions 27 and 28 respectively.

For a purpose hereinafter appearing, blocks 33 are positionedupon themembers 3 which blocks have the stub shafts 31 and 32 journaledtherethrough, the said stub shafts carrying upon their inner ends bevelgear wheels 34 and 35. The blocks are provided with offset portions36which receive one end of the rods 37 which carry the bevel gear wheels38, the last named beveled gear wheels adapted to mesh with those firstmentioned as is clearly shown in Fig. 1. Provided upon the blocks areextensions 39 to which are connected the beams-4:8 which point of theplow, thus decreasing the work usually performed by that membern' Gearwheels 43 are provided on the rear ends of the rods 37, the said gearwheels meshing with other gear wheels 44: as shown, whereby motion isgiven to the shafts 4:5 upon pletely pulverized. The screws 46, act as82, support the shafts 37 and i5.

draft means to impart a forward thrust and also serve to draw the earthonto the plow blades and the screws are tapered rearwardly toaccommodate the contour of the plow blades and so that the screws canextend substantially the entire length of the blades. Thus the screwscan be arranged abreast of the plow blade to directly coact therewith.Further, the screws 46 are conned to conform to the shape of the moldboards so as to lie closely adjacent thereto and effectively coacttherewith to break up the earth upturned by the shares. Frames 76-77 and7 8 -7 9, fastened to beams 48, at 8081 and Supporting the plow blades47' are the beams l8 which are pivoted at their endsas shown andprovided with the arms 4:9 which have pivotal connection with the links50, the said links being operated by the levers 51 which carry pawls 52adapted to operate upon the segmental racks 53. Pivoted handles 52 areprovided upon the levers 51 which operate the pawls 52 as clearlyillustrated, the plows and screws thereof being lifted together. r

The rear end of the lever 15 is provided with the handle 54 and isadapted to be held in different positions through the medium of the rack55 which is mounted upon the cross piece 56 as shown.

The operators seat is supported upon the frame work through the mediumof the leaf springs 58 and 59; It will now be readily obvious that theoperator within his seat can easily control the different levers abovementioned. I find it'advantageous to provide some eflicient means forguiding the machine in itstravel and to this end the rear of the'frameis provided with a casterwheel 60 which has connection with thebifurcated end 61 of the rod 62' which is insorted in the sleeve 63 asshown. The sleeve 63 is provided with the extension 64: and is adaptedto be secured tothe frame work beneath one end of the leaf spring 59.For more securely supporting the rod 62, the members 65 are provided,which members have connection with the same intermediate its ends andwith the under side of the frame as shown at 66. A segmental rack 67 isprovided 1 upon the rod 62 which rack meshes wit th ie ar.W .68 S pp y Pn ling said structure for the 69 in the block 7 O which is supported bythe substantiallyUshaped bracket 71. For the purpose--of receiving thesprocket chain 72,

pin 69 is provided with a second gear wheel,

without the" necessity of the operator leaving his post. p 7

It is thought thatthe operation of the machine will be understood fromthe foregoing description and a detailed disclosure of the same isthought to be unnecessary.

I desireto be understood that I may make slight changes in theconstruction and combination of the parts of my machine withoutdeparting from the spiritof the invention in the least, provided suchchanges fall within the scope of the sub-joined claims. 7
